Bounding box graphic helpers
centerOrthoBBox :: (Real u, Floating u, Ord u) => Radian -> BoundingBox u -> BoundingBox uSource
centerOrthoBBox : theta * bbox -> BBox
Rotate a bounding box by theta about its center. Take the
new bounding box.
Remember that bounding boxes are always orthonormal rectangles, so the dimensions as well as the positions may change under rotation.
emptyBoundedLocGraphic :: InterpretUnit u => BoundedLocGraphic uSource
Build an empty LocGraphic returning a bounding box.
The emptyBoundedLocGraphic is treated as a null primitive
by Wumpus-Core and is not drawn, although it does generate
the minimum bounding box with both the bottom-left and
upper-right corners at the implicit start point.
emptyBoundedLocThetaGraphic :: InterpretUnit u => BoundedLocThetaGraphic uSource
Build an empty LocThetaGraphic returning a bounding box.
The emptyBoundedLocThetaGraphic is treated as a
null primitive by Wumpus-Core and is not drawn, although
it does generate the minimum bounding box with both the
bottom-left and upper-right corners at the implicit start point
illustrateBoundedGraphic :: InterpretUnit u => Image u (BoundingBox u) -> Image u (BoundingBox u)Source
Draw a BoundedGraphic, illustrating the bounding box.
illustrateBoundedLocGraphic :: InterpretUnit u => LocImage u (BoundingBox u) -> LocImage u (BoundingBox u)Source
Draw a BoundedLocGraphic, illustrating the bounding box.
illustrateBoundedLocThetaGraphic :: InterpretUnit u => LocThetaImage u (BoundingBox u) -> LocThetaImage u (BoundingBox u)Source
Draw a BoundedLocThetaGraphic, illustrating the bounding box.
bbrectangle :: InterpretUnit u => BoundingBox u -> Graphic uSource
Draw a bounding box as a stroked rectangle with dotted lines.
boundedRect :: InterpretUnit u => DrawMode -> u -> u -> BoundedLocGraphic uSource
boundedRect : style * width * height -> LocGraphic
Create a stroked rectangle - the implicit start point is bottom-left, return the bounding box of the rectangle as the answer.
The line properties (colour, pen thickness, etc.) are taken
from the implicit DrawingContext.
